Changed healthcheck from localhost to 127.0.0.1 to force IPv4 connection.
The issue occurred because 'localhost' resolves to IPv6 (::1) but nginx
only listens on IPv4 by default, causing healthchecks to fail.
Error before fix:
Connecting to localhost ([::1]:80)
wget: can't connect to remote host: Connection refused
Updated both Dockerfile and docker-compose.yml for consistency.

Removed .github/workflows directory as the application is now fully
static and deployment workflows are no longer needed. The app can be
deployed to any static hosting platform without CI/CD pipelines.
Static deployment options:
- Vercel, Netlify, Cloudflare Pages (zero config)
- GitHub Pages, S3, CDN
- Self-hosted nginx/Apache
- Docker (optional)

Replaced REST API dependency with @valknarthing/pastel-wasm (130KB) for
complete browser-based color operations. The application is now fully
static (2.2MB total) with zero network latency and offline support.
**Key Changes:**
1. **WASM Integration:**
- Added @valknarthing/pastel-wasm dependency (0.1.0)
- Created lib/api/wasm-client.ts wrapper matching API interface
- Updated lib/api/client.ts to use WASM client by default
- All 18 color operations now run locally in browser
2. **Static Export Configuration:**
- Changed next.config.ts output from 'standalone' to 'export'
- Disabled image optimization for static export
- Removed API proxy route (app/api/pastel/[...path]/route.ts)
- Updated package.json scripts (removed dev:api, added serve)
3. **Docker Optimization:**
- Migrated from Node.js standalone to nginx-alpine
- Created nginx.conf with SPA routing and WASM mime types
- Updated Dockerfile for static file serving
- Reduced image size from ~150MB to ~25MB
- Changed port from 3000 to 80 (standard HTTP)
- Simplified docker-compose.yml (removed pastel-api service)
4. **Documentation Updates:**
- Updated README.md with WASM benefits and deployment options
- Added Key Benefits section highlighting zero-latency features
- Rewrote deployment section for static hosting platforms
- Updated CLAUDE.md tech stack and architecture
- Removed obsolete docs: DEV_SETUP.md, DOCKER.md, IMPLEMENTATION_PLAN.md
**Benefits:**
- 🚀 Zero Latency - All operations run locally via WebAssembly
- 📱 Offline First - Works completely offline after initial load
- 🌐 No Backend - Fully static, deploy anywhere
- ⚡ Fast - Native-speed color operations in browser
- 📦 Small - 2.2MB total (130KB WASM, 2.07MB HTML/CSS/JS)
**Deployment:**
Can now be deployed to any static hosting platform:
- Vercel, Netlify, Cloudflare Pages (zero config)
- GitHub Pages, S3, CDN
- Self-hosted nginx/Apache
- Docker (optional, nginx-based)

The previous implementation had misaligned padding structure:
- Navbar/Footer: padding INSIDE max-width container (max-w-7xl mx-auto px-8)
- Page content: padding OUTSIDE max-width container (px-8 on outer, max-w-7xl inside)
This caused content to have double horizontal spacing and misalign with
the navbar and footer borders.
**Fix:**
Move px-8 from outer container to inner max-w-7xl container on all pages,
matching the navbar and footer pattern.
**Structure (all components now consistent):**
```
<div className="py-12"> <!-- vertical padding only -->
<div className="max-w-7xl mx-auto px-8"> <!-- max-width + horizontal padding -->
<!-- content -->
</div>
</div>
```
Now navbar, main content, and footer all align perfectly at the same
left and right edges.

The previous implementation had inverted logic that prevented keyboard
shortcuts from working. The check `shortcut.ctrl ? event.ctrlKey : !event.ctrlKey`
meant that if ctrl wasn't specified, it required ctrl to NOT be pressed,
which broke shortcuts with only meta keys.
**Changes:**
- Fix modifier matching: only check modifiers that are explicitly required (=== true)
- Add check to prevent unwanted modifiers (e.g., if only meta+c, reject ctrl+meta+c)
- Improve cross-platform meta/cmd key handling (Mac uses metaKey, Windows/Linux uses ctrlKey)
- Allow meta key to permit ctrl on non-Mac platforms (meta is treated as ctrl equivalent)
**Now working shortcuts in playground:**
- Cmd/Ctrl+C: Copy color to clipboard
- Cmd/Ctrl+S: Share color (copy URL)
- Cmd/Ctrl+R: Generate random color

Ensure consistent spacing and alignment between header, main content, and footer:
- Update Navbar to use max-w-7xl and px-8 (matching Footer)
- Standardize all page containers to use px-8 py-12 padding
- Change home page from max-w-5xl to max-w-7xl for consistency
- Update all 12 pages to use consistent padding (px-8 py-12 instead of p-8)
This creates a unified visual alignment across the entire application,
with all content sections (navbar, main, footer) using the same
max-width (7xl) and horizontal padding (px-8).

Replace build-time NEXT_PUBLIC_* environment variables with server-side
runtime configuration. This allows changing the Pastel API URL without
rebuilding the Docker image.
**Changes:**
- Add Next.js API proxy route at /api/pastel/[...path] for server-side proxying
- Update API client to use proxy endpoint instead of direct API URL
- Replace NEXT_PUBLIC_API_URL with server-side PASTEL_API_URL
- Remove build arguments from Dockerfile (no longer needed)
- Simplify docker-compose.yml to use runtime environment variables only
- Update all .env files to reflect new configuration approach
- Add comprehensive DOCKER.md documentation
**Benefits:**
- No rebuild required to change API URL
- Same image works across all environments (dev/staging/prod)
- Better security (API URL not exposed in client bundle)
- Simpler deployment and configuration management
**Migration:**
Old: NEXT_PUBLIC_API_URL (build-time, embedded in bundle)
New: PASTEL_API_URL (runtime, read by server proxy)
